preferably formed `with closed loops `17 at its outer end andto which is connected an extension link 18, `adapted to be connected at'its outenend to one side of the 'anti-skid device. The opposite side of theanti-skid device is connected to the clamping arms 14 and 15'by a locking link 19, the same being provided at'its nter end with a closed loop 20, by which it is secured or attached to the anti-skid means, and is' formed at its inner end withv ay cross-bar 21 thatjsl adapted to Span'letween the free ends of the clamping arms and whose extreme end is pivoted to one of said clamping arms as indicated at 22.

VEach o'fsaidclampin -arms is refera'bly formed ofvlat inetal an is provi ed with a closeddoop 23 at one end and is bent rangularly at its other end to form an outwardly projecting ear24, the ear on arm l14 being provided with aperoration 25', which forms the pvot openin for the end of the lockinglin t 19. Closed loo s 23 are referahly formed by eoililng tige ends o the clam-ping arms back upon themselves, so as to provide elongated bearings, and the same are preferably pivoted. upon spaced sidebars 26 of the lsupporting-link 16. Said clamping arm's 14 and 15 are also curved slightly and are positioned to dispose their concave faces opposite each other, whereby they will curve aromda spokelB and po# sition their ends in relative close' relation. `1Supportinglink 16 is preferably formed oflieavy gage wire, and is bent intermediate its ends to forina'closed loop having the spaced Side-bars 26 connected at one end by the cross-bar 27 and having their opposite ends bent inwardly toward each other until they contact. The ends are then extended in parallel relation to form the dou'ble shank 28, thejnpper ends of which are bent backwardly to form the loops 17. Extension link 18 can 'be of any desired shape, but is preferably formed with a single strand of heavy gage wire having its en s bent backwardly to form the closed loops 29 and 30.

Locking link 19 is also preferably formed of .heavy vgage .Wire and 1s bent at one end to form e 'Ufshaped loop, one extremity of which is flattened to receive the pivot 22. As shown, the locking link ispivoted to the rear-side of one of the'ears 24, so that, when said link is thrown to locking osition its cross-bar 21 will lie parallel wit the edges of the clamping arms, and its lon'g arm will engage bac o the other ear 24 and also against the outer side of the clamping arm. Thus the short arm being pivoted to one of the -clamping arms, the long arm will serve as a lever to perform the clampingv action around the spoke.

To protect the spokes from injur a pad.

31 is provided for each of the c amping arms. Said pads are formed by wrapping any suitable material around the arms and 'securing them in place with spurs 32 which are -punched from the. body of the arms. Preferably the spurs are punched outwardly from the arms, so that t ey will lie on'the outside ofthe arms and pads, thereby presenting a smooth surface on the inner side of the arms. 1

This improved attaching means can be used with various types of anti-skid means, but in the present instance,.it is shown in connection with. an anti-skid means shown, described and claimed in an apfleication for atentA having a Serial Num ,r 201,789.

his articular anti-skidmeans embodies a tread ook which is adapted to extend transversely yof a tire and which is' provided with $0 certain'l shaped connectil links at each end,4

links, Similar to the end links beingho those shown in the present drawin and 34, and it is to these hook-links t at the,4

outer ends of the locking-link 19 and exten 35 sion link 18 alre connected. It will be observed, that whenv the locking-link 21 is thrown to 'locking ition and its free end is connected with t e hook-link 33, that it is retained in its locking ition by its con- 40 nection with the anti-skld means. In other words it cannot be turned Ibackward on its pivot, or be, thrown to unlockin gosition, until 'its free end is disconneete om the anti-skid means. To facilitate the eonnectin o eration bef tween the lockin link 19 an t e anti-skid means, the particularly constructed hookl link 33 has been provided. This link is preferably formed of flat metal and is formed with a closed loop 34 at one end and ano en hook 35 at its opposite end, the termina of said hook being bent to form an upstanding lug 36 with which is adapted to engage the free en d of a pivoted spring latch-plate, -whieh ,has an o ening to engage over the lug 36. To unlock tlJiis hook link, it is necessary to bend the spri -late upwardly to disengag'e the lug 36, alii? t en turn it on its pivot in a direction away from the hook, where it will remain until manually operated in the opf `posite direction. It thus provides a hook fastener having a spring closing tongue, which does not have to be held oplen by the o erator while he is connecting t e locking link thereto. This is an important feature, as it has been found that considerable trouble has been caused by using other types of spring snap fasteners.

T o adapt this improved attachment mea to tires o .various sizes or to diferent ty s of anti-skid means, the llocking-.link 19 and the extension link 18 are usually placedupon the market straight, or without the u perloo s 20 and 30, as indicated in dotted ines 1n `1g. 3 of the drawing. In this condi 'on, 75 the loops 2O and 30 can be formed ny oint intermediate the length of these memers 18 and 19, thereby making said members either long or short as the sizel of the tire or the type of anti-skid means demands.

The diameters ,of spokes also vary, and to adapt the attachment to different sizes, arms 14 and 15 can be made slightl resilient, so that one width of U-loop on the lockinglink can be used, 'butdpreferably the clam 35 ing arms are rigid, an in that case. the loc ing links are placed upon the market straight, without the U-loop and the closed loop 20, as indicated in dotted lines at 37 in Fig. 3 of the drawing, so that both the U- loop and loop 20 can be formed after the size of the spoke is ascertained. Or the deviceY can, be placed u n the market with U- loops of different wi ths, to enable the buyer to select the size desired.- g5

It will also be understood, that supporting link 16 can be made lon enough to engage directly with the hookink 34, thereby obviating the use of the extension link 18, but lto secure a reater flexibility, and for folding, it is pre erableto use the extension link 18.

Locking-link 19 can be formed with a loop 38 to serve as -a pivot'joint, as indicated by dotted' lines in Fig. 4, in lace of rovidin a pivot stud as shown in t e other Egures o the drawings.

From the above description, it will be seen that the device is strong, simple in construction and cheap -to manufacture, and will securely retain' the antiskid means in its roper position on the tire, and without 4in- ]ury to the wheel. Furthermore, it is adapt-r ed for various adjustments, so that it can be formed to fit spokes and tires of different sizes and also ierent types of anti-skid means. j

While it is referable to use a locking-link 19 made of eavy wire, as shown in the drawing, it will be understood, tlat a small link chain tan be secured to one of the clampin arms and be pulled around the other arm behind its ear 24, to operate the clamping arms to clampin osition.

This attachment after cmg secured to an anti-skid means to properly t a certain diameter of tire, forms' a unit which can beI easily attached or detached from the wheel, even should the operator be wearing gloves.
